Anti-freeze poisoning in pets

As the weather gets colder many of us will use anti-freeze in our car engines, but while it’s convenient for us, it’s also very dangerous to our pets.

While many people may think, ‘why would my cat or dog go near anti-freeze?’ well, Ethylene glycol- the main ingredient in most anti-freeze brands has an inviting aroma and sweet flavour. Its appealing smell and taste often tempts animal into tasting it.

Anti-freeze is found in car radiators and some screen washes, but it is extremely toxic to both dogs and cats. As our pets like drinking from ditches, puddles and ponds, it could mean they’re prone to drinking water contaminated with anti-freeze. Anti-freeze can also be found in some inks and snow globes.

The active ingredient of many anti-freezes, ethylene glycol, is rapidly absorbed into the body after drinking. Within hours it causes severe kidney damage, which is very difficult to treat. In one report involving 25 cat cases, 96% of those affected died.

Signs & Symptoms

Some common signs of antifreeze poisoning in dogs and cats include:

  • Drunken behaviour
  • Euphoria/Delirium
  • Wobbly, uncoordinated movement
  • Nausea/Vomiting
  • Excessive urination
  • Diarrhoea
  • Rapid heart beat
  • Depression
  • Weakness
  • Seizures/Convulsions/Shaking tremors
  • Fainting

Treatment

If you suspect your pet has drunk some anti-freeze, it’s important you contact us ASAP. If your cat or dog is treated immediately after exposure it has a far greater chance of survival. However your pet will need intensive treatment. Tragically, the survival rate is very low if the kidneys have been damaged and poisoned pets often have to be put to sleep.

Prevention

Anti-freeze is one of the most life-threatening poisonings that vets see, but there is a safer alternative. Propylene glycol anti-freeze is more expensive but safe for pets and other wildlife. All anti-freeze products should be labelled to show its contents, so please check these before purchasing and avoid products with Ethylene glycol.

 

Keeping chocolate out of reach this Christmas

Christmas is a time where chocolate isn’t usually in short supply and with it being a very busy season, it’s easy to get swept up in the occasion and often forget about leaving advent calendars and chocolate treats lying around, but if your pet does manage to get hold of some chocolate it can endanger their health, sometimes seriously, and even innocent treats can be deadly.

The reason chocolate is poisonous is because it contains a chemical called theobromine and while we usually focus on dogs due to their appetites and their amazing ability to steal food, please note that this chemical is not only poisonous to dogs, but is also poisonous to other animals such as cats, rodents and rabbits.

Although any chocolate should be kept out of reach of your pets, it’s important to note that the darker and more expensive chocolate usually contains more theobromine, which can make the fancier chocolate more poisonous.  Although white chocolate contains less theobromine and is less likely to cause chocolate poisoning, it’s still very fatty and can still make your pet ill.

If any of your pets do eat some chocolate, depending on their size and the amount they’ve consumed, initial signs and symptoms can be vomiting and diarrhoea. Chocolate is also a stimulant and can lead to your pet to become excitable, as well as developing muscle twitching, tremors, fitting and life threatening problems with their heart and severe cases can be fatal.

Over the Christmas period make sure that all chocolate is out of the reach, this includes chocolate decorations hung from your tree, advent calendars, boxes of chocolate put out on Christmas day, and one that many people forget is the wrapped chocolates under the tree (most pets have a great sense of smell and can easily get into these chocolate treats).

Although chocolate wrappers are not poisonous, they can cause an obstruction in the gut if eaten.  This can be very dangerous and may require surgical intervention.  Signs of an obstruction may include vomiting, lethargy, your pet being off their food, not defecating or finding it difficult to defecate.

If you think your pet has eaten some chocolate, please contact us for advice about what to do next.
